Power Planner: Homework/Grades play online

Power Planner is the ultimate homework planner for students, featuring online sync with Windows and iOS apps, grade calculation, widgets, automatic reminders, and more.

With Power Planner's online account, you can stay on top of homework assignments and schedule from your desktop, iPhone, Android, or web browser!

Power Planner lets you manage semesters, enter classes with time schedules and room locations, add assignments and exams, receive automatic reminders about upcoming homework, and more.

The widgets allow you to see your upcoming homework. You can also pin a schedule widget that tells you when and where your next class is.

Grade and GPA calculation is also fully supported, allowing you to know exactly what your GPA is across multiple semesters.

Google Calendar integration lets you see your classes and homework from Google Calendar!

The paid version (one-time purchase) unlocks the ability to add more than five grades per class, use multiple semesters/years, and more. It is purchased through an in-app purchase, and when you buy Power Planner once, you unlock it everywhere. However, the free version is still perfectly functional.
